Le Vercors : un massif de la moyenne montagne alpine, 1984, Delannoy, J. J.
THE VERCORS: A MASSIF OF MIDDLE ALPINE MOUNTAIN - The Vercors is a forested massif of middle mountain, in the French Northern Prealps. The characteristic of the Vercors massif is the thick and massif urgonian limestones, which underlines a folded structure. The Vercors quickly hold the attention of speleologists, who had put forward the density and diversity of karstic aspects since the beginning of the century. Landforms display glacial karstic landscapes more or less damaged in terms of bio-climatic levels of mounts and depressions landscapes and of deep water gaps, which main flows of the massif are flowing in. The notion of the morphoclimatic heritage applies to the underground karst for which glacial quaternary episodes have been determinant in the large systems genesis (gouffre Berger - Scialet de la Fromagre, Antre des Damns, Combe de Fer...). The study of underground deposits allows to bring up-to-date various period of karst development; a preglacial stage (e.g. upper levels of Cuves de Sassenage, Gournier, Coufin-Chevaline...). The study of the current dynamic shows that the Vercors as an important karstic ablation, between 120 to 170mm/ky. The karstic dynamic exerts mainly on the superficial slab of the massif (from 80 to 50% of the whole ablation). The Vercors can be considered as the best example of calcareous massif in temperate middle mountains, thanks to the combination of various favourable parameters: pure karst rocks, morpho-climatic episodes not constraining, and a high karstic dynamic.

Mesure de la propagation dune perturbation de pression au Trou qui Souffle (Maudre, Isre), 1993, Lismonde, B.
The Trou qui Souffle (Breathing Pot) is a cave in Vercors. There are three entrances, two of which are known and are situated 2 km apart. With one entrance rapidly obstructed, the effect upon the velocity of wind was measured at the other. The findings were a speed of about 100 m/s

La crue du 18 mai 1994 au Trou qui Souffle (Vercors, France), 1995, Lismonde B. , Les_splos_grenoblois_du_c. A. F.
The syncline of Autrans--Maudre is located in Vercors, an alpine region of France. This karstic basin is drained by the resurgence of Goule Noire, located in the gorge of the Bourne River. The surface of this region is 80 km2 and the flow of Goule Noire in low water is 500 1/s. The stage of limestone is urgonian and senonian. The most important cave is the Trou qui Souffle (blowing cave). This cave is 40km long and 450m deep. Down, sumps stop the explorations. The water volume stocked in the phreatic passages between the cave and the spring is about 1,000,000 m3. The Trou qui Souffle has two great fossil galleries, the Franois gallery and the gallery of Easter. The water way of phreatic gallery is actually unknown. In may 1994, a very high rain of 155 mm in a day caused a great flooding. In the cave, the piezometric level went up 100 m over the normal level; 14km of passages are drowned. All the Franois fossil gallery are fill with water. On the contrary, the Gallery of Easter is dry remained. The analysis of this exceptio-nal phenomenon (of 50 years recurren-ce) shows that a very little passage exists between Trou qui Souffle and Goule Noire. The equivalent duct diameter is about 1,5 m. The Trou qui Souffle stocked a water volume of about 300 000 m3. So the karstic system atte-nuates the crest of floods and regula-rizes the flow of resurgence.

Le Luirographe : tude de la crue du 22 avril 1995 (rseau de la Luire, Vercors), 1996, Morel, L.
The Luirographe can record automatically parameters such as the water height in a karstic network. Placed at the beginning of April 1995, at -200 m, it recorded for the first time the Luire swelling, which lasted two days. The cave of the Luire is situated in the massif of Vercors, with an hydrogeological basin of 230 km2. The Vercors is a forest of middle mountain within the French Pre-Alps of the North. The Luire swelling only exits when there are very big nival spate accentued by important rainfalls and by a southern wind. Such event arrives only every other year on average. The difference between the high and low level of karst flood can reach the impressive height of 475 m, the most important known in the world. It is the difference between altitude of saturated zone where there is the continuous spring of Arbois and the temporary emergence of the Luire, known up to -451 m and are 20 km apart.

Intrt des sdiments dtritiques endokarstiques en tant quarchive naturelle ? Discussion autour des dpts lacustres souterrains (Grottes de Choranche - Vercors), 2006, Perroux Annesophie
Interest of endokarstic detritic sediments as a natural archive? Discussion on underground lacustrine deposits (Choranche Caves Vercors) - Among the various natural environmental archives, the underground detritic deposits remained hitherto forgotten, in particular for high resolution analyses and treatments. Through the study of the sedimentary accumulation of the Cathedral Lake (Choranche Caves, Vercors), this paper shows the potential of information which these deposits contain. Sedimentary cores were sampled in the lake, various data are measured (granulometry, spectrocolorimetry, magnetic susceptibility and gray level imagery), then submitted to statistical processing (PCA, Passega images...) and signal treatment (wavelet decomposition). The stratigraphy of charcoal fragments trapped in the sediment and dated by the 14C method, does not appear sufficiently coherent to propose a satisfying age-depth model. Only some dates make it possible to suppose that the sedimentary filling of the lake covers at least the 4000 last years, with an average rate of sedimentation estimated at 1.87mm/yr. The other results of this work make it possible to understand transport and deposition dynamics of the sedimentary particles in an endokarstic lake, in particular with regard to flooding episodes. The Cathedral lake has a binary functioning, with mainly a fine sedimentation (decantation), punctually stopped by flooding episodes, which on their turn have two different dynamics (brutal or progressive phenomena in sedimentation). Lastly, the study of various signals highlights a great number of sedimentation control factors; these factors seem to act mainly on small time scales (more than 80 % of the granulometric signal variation are linked to phenomena with a period inferior to 40 years, according to the chronological framework supposed in the first assumption). This work carried in Choranche shows that endokarstic detritic sediments contain high resolution archives of the environmental evolutions. Subject to a chronological positioning more precise than the one we have today, paleoenvironmental interpretations and reconstitutions will make it possible to go further in their reading.
